Application filed July is; 1907. Serial No. 383,584.

To all whom it may concern: Be it known that 1, CHARLES DUEMER, acitizen of the United States, residing at Hamilton, Ohio, have inventeda new and useful Improvement in Centrifugal Hydro-Extractors, of whichthe following is a specification.

My invention relates to centrifugal hydro extractors of the classadapted to the use of laundries, paper mills, sugar. refineries andelsewhere, and the objects of my improvements are to form the basket orcage of a single casting of aluminium bronze, or other suitablenon-corrosive metal alloy; to reinforce its walls with one or moreintegral bands; to provide its walls and bands with perforations; torovide a conical bottom which is gradua y increasedv in thickness towardthe center; to provide it with an integral taper bearing and to providechea and durable. construction combined wit facility of operation andefliciency of action. These objects are attained in the followingdescribed manner as illustrated in the accompanying drawings, in which VFlgure 1 1s a vertical diametrical section of .a centrifugal hydroextractor embodying my lmprovements; Fig. 2, an elevation and Fig.

3 a plan of the perforated basket.

In the drawings, 1 represents the preferably cylindrical curb of theusual construction and su ported on base 2 by means of harge columns 3.A cylindrical flange 5 is secured on the base concentric with thevertical axis of the curb.

A quill 6 is provided with an annular flange 7 near its lower end andwith a hooded or flanged nut 8 adjustably threaded on its upper end.Elastic rings 9 interposed between flange 7 and nut 8 and within thesupport on the respective opposite sides of flange 5 therein serve to ieingly maintain the quill in its norma vertical position. A spindle 11formed with a tapered top end 12 is journaled within .the quill andprovided with a pulley 13 which is provided with an annular bottomflange 14 and overhangs the support 4 with the center of its face in theplane of flange 5.

The cylindrical basket or cage 15 consists of a single casting ofaluminium bronze or other suitable non-corrosive alloy. It is formedwith a conical bottom 16 which is gradually thickened in cross sectiontoward the center where it is provided with a vertically de endingtapered bearing 17 adapted to detac ably engage with the tapered spindle11, whereby the basket may be rotatively supported within the curb asshown in Fig. 1.

The thin side wall 18 of the basket is formed with one or more exteriorreinforcing rings 19 and the top wall 21 is gracefully curved toward thecenter and terminates in a thickened edge or smooth ring 22 whichencircles the top opening 23. The side wall and also the rings 19 areforaminated or provided with a multiplicity of small perforations 24. IIn operation, the mounting of the quill between the elastic ringsprotides for a gymtory motion of the rotating basket that it may conformto the center of gravity of its contents in the usual manner. The integrusual difficulty of assembling the bottom, the top ring and thereinforcing rings with the foraminous side wall and wlth sufiicientaccuracy to secure the proper balance necessary for its most efficientact-ion.

The single piece basket may be turned and al 75. construction of thebasket obviates the- In a centrifugal hydro. extractor, an ex- Itracting basket consisting of a single casting from a non-corrosivemetal formed with a thin lateral wall reinforced circumferentially byrings or ribs integral therewith and foraminated throughout and throughthe ribs as Well, the upper end of the basket ta ering spherically tothe opening about whic is a reinforcin roll formed integral with thebasket, and t e bottom of the basket thickened gradually from the outeredge towards the middle and there provided with a depending integral lughaving a tapering seat for the rotating spindle, substantially as andfor the purpose set forth.
